To all whomz'tmaxy concern:

Be it known that I, Enema Ltmwio MiiLLER, a citizen of the GermanEmpire, residing at Berlin, Germany, have invented certain new anduseful Improvements in Safety Razors rior which I have filed anapplication in rmany May 14, 1919), of which the following is aspecification.

My invention refers to safety razors and more especially to the bladesused in connection therewith. As is well known people with very delicateskin refer being shaved With as rigid a razor or lade as possible. It ismoreover important for such people that 35 they should be shaved at avery small angle of inclination of the razor, this being most essentialfor the clear shaving of concave parts of the face such as certainportions of the throat or for shaving the moustache. A0- cording to thepresent invention now these demands are complied with by the section ofthe blade being given the shape of a flat roof with a hole in the middlefor directly fastening the handle in the blade. In order to comply withthese requirements I prefer forming theblade section either like a fiattriangle or like a segment. In the drawings aflixed to thisspecification and forming part thereof two differ cut modifications of asafety razor embodying my invention are illustrated by way of example.In the drawings- Fig. 1 shows a safety razor with triangleshgped blade,5 ig. 2 a safety'razor with segment-shaped blade,

Fig. 3 is a. plan of the blade shown in Fig. 1.

1 is the handle, 2 the blade, 3 the protective comb. The blade isprovided in the middle with a hole 5 fitted with female thread, whichthe handle 1 is screwed into. In the face of the blade averted from theskin a groove 6 is provided, which is deep E enough to allow both blades7 to lie flat upon the grindstone when being ground. The upper surfaceof the roof-shaped blade on one or both sides of the blade resembles thesurface of a sphere, a cone or the like; the blade in Fig. '1 is shapedon its left half like a cone, while its right half is level. The bladein Fig. 2 is shaped like a sphere on both sides. As shown in Fig. 3, aconvex two faces are in touch during the polishing,

while the conical shape allows of touch .in a line only.

By making one half of the blade straight, the other half curved, asshown in Fig. 3, the differently curved portions of the face can beshaved equally well.

The safety razors in use till now, in which a handle is screwed into theblade with the protecting comb underlying it, require special appliancesfor securing these parts relatively to each other in assembling them.Moreover the blade cannot easily be handled in mounting and dismounting;if handled clumsily it will either slip or injure the hand. According tothe present invention these disadvantages are avoided by aid ofindentations 4 arranged in the blade and in the protecting combrespectively. The fingers are laid in these indentations, and thus bothparts are secured relatively to each other that they can be placed onthe handle without using any set pins.

I claim:

1. In a safety razor apparatus, a blade having on one side, and at eachedge of the blade, cutting edges offset from the main portion of thebody of the blade, including two plane surfaces 1 ing in the same plane,a guard comb beneat the blade and ahandle extending through a centrehole of the blade and fastened therein.

2. In asafety razor apparatus, a blade having on one side, and at eachedge of the blade, cutting edges offset from the main portion of thebody of the blade, including two plane surfaces lying in the same plane,a guard comb beneath the blade and a handle extending through a threadedcentre hole of the blade and fastened therein.

3. In a safety razor apparatus, a blade having on one side, and at eachedge of the blade, cutting edges-offset from the main portion of thebodyof the blade, including mews? two plane surfaces lying in the sameplane, the fingers in the concavities and thereby re a guard combbeneath the blade and a, handle mining them in position so that they canextending through a centre hole of the blade be fixed upon the handleWithout the aid of me and fastened therein, both the blade andprojecting pins.

the guard comb being provided with wide In testimony Whereoi I affix mysignature, and gently curved concavities whereby both these pants can belaid hold of by placing EUGEN L. MULLER.
